"I put a jumper on the on/off front panel connector pins."

Heh, there's your problem...

Either you'll get a real "power"-!button!, or remove the jumper shortly after you plugged it in...

Updated to Bios to MOPNV10J.86A.0209. But still, the ECP port is not detected properly.

I would like to report an ACPI/PNP Bios problem which prevents

the correct detection of all parallel port parameters.

I've patched the latest BIOS (MOPNV10J.86A.0175) onto the system, but still

neither Linux nor Windows are able to detect the correct parallel port setting and

will only operate in compatibility, unidirectional PCSPP mode.

This is very unfortunate, because some hardware (purposely-built stuff and

some old scanner/streamer too) still rely on this type of interface.

The reason for this screwup is pretty simple to spot. The BIOS does not

generate the necessary ACPI/PNP0401 entry, once the parallel port mode

is set to ECP. Instead, it continues to report a simple PNP0400 device.

This in turn will force the operating system to operate parallel port interface

in "1980 mode".
